Description:
SEVERE COMBINED IMMUNODEFICIENCY, AUTOSOMAL RECESSIVE, T CELL-NEGATIVE, B CELL-NEGATIVE, NK CELL-NEGATIVE, DUE TO ADENOSINE DEAMINASE DEFICIENCY
ADENOSINE DEAMINASE; ADA
IDENTIFICATION OF SPECIES OF ORIGIN |
Species of Origin Confirmed by Nucleoside Phosphorylase and Lactate Dehydrogenase Isoenzyme Electrophoresis |
|
adenosine deaminase |
According to the submitter, biochemical test results for this subject showed decreased enzyme activity. EC Number: 3.5.4.4; <50% activity. |
|
Gene |
ADA |
Chromosomal Location |
20q13.11 |
Allelic Variant 1 |
608958.0010; ADA DEFICIENCY, PARTIAL |
Identified Mutation |
ARG76TRP; In cell lines GM05816, GM06200 and GM07103, Hirschhorn et al. [Proc Natl Acad Sci U S A 87: 6171 (1990)] found a C-to-T transition at nucleotide 226 resulting in a change of arginine-76 to tryptophan. |
Remarks |
Clinically unaffected; <50% of normal RBC ADA enzyme activity; donor subject has one allele which has a C>T transition at nucleotide 226 in exon 4 of the ADA gene [226C>T] resulting in a substitution of tryptophan for arginine at codon 76 [Arg76Trp(R76W)]; affected child is GM06200. |
